Abstract:

 Background and objectives: Cross-linking of the corneal collagen is regarded as a new treatment technique for a non-inflammatory thinning disease of the cornea-known as keratoconus, to strengthen the biomechanical elements of the cornea. Riboflavin (Vit.B2) and UV-A light have been shown to be effective at stopping progression of keratoconus.   Aim: to evaluate the effects of collagen cross-linking in patients with keratoconus. Methods: A retrospective, non-controlled study was performed on forty-five patients (64 eyes) with keratoconus in whom collagen crosslinking was done between years (2017-2021). It was conducted in Bright Eye, Tooe Maleek, and the Eye Center private hospitals in sulaimaniya city. We measured the distance visual acuity with and without glasses (Snellen acuity chart and decimal notation), the, the spherical equivalent and cylindrical refractive error (autorefractometer), the central corneal thickness and the mean keratometic reading (corneal topography). These were taken before and after crosslinking in a period between 6-12 months, and then t-test was used to compare and analyze the results. Results: After comparing the pre- and post-crosslinking findings, we found an improvement in the uncorrected VA (by 0.06±0.04) and best corrected VA (by 0.10±0.03). The central corneal thickness was decreased by a mean of (13±12µm) and the mean keratometric reading decreased by a mean of (0.9D). However, each of the spherical equivalent and cylindrical refractive errors showed no significant difference before and after the procedure (stabilized). Conclusion: The procedure (collagen crosslinking) was efficacious in stopping progression of the disease.
